DETAILED DESCRIPTION

FIG. 1 illustrates an overview of a computer program 10 according to oneembodiment. The computer program 10 is configured to be executed on acomputer device for dynamic modification of audio content. The audiocontent theme comprises audio information relating to at least one themevariation. The amount of audio information corresponds to the amount ofcomplexity in the audio data waveform. The computer program 10 isconfigured to store an intensity parameter 20 on the computer deviceindicative of an amount of audio information being played and avariation parameter 30 indicative of at least one theme variation of theaudio information being played. The computer program 10 is configured tomodify, based on a modification of said intensity parameter 20, theamount of audio information being played and, based on a modification ofsaid variation parameter 30, the at least one theme variation of theaudio information being played. The intensity parameter 20 and thevariation parameter 30 may be modified through a user input.

The computer program 10 for dynamic modification of audio informationcomprises a plurality of audio files. Each of the audio files may havebeen recorded before being entered into the computer program 10. Inorder to obtain a good result the audio files in the audio content thememay have the same beats per minute and duration. The audio file maycomprise any plurality of sounds or instruments. However, in order toobtain an improved result of the dynamic modification of audio content,the music files have to be carefully recorded, so that a plurality ofmusic files only differs from each other by having different amount ofaudio information being played, and so that a plurality of music filesonly differs from each other by having different theme variations ofaudio information being played. When using an audio content theme allaudio files in the audio content theme are started simultaneously. Theintensity parameter 20 and the variation parameter 30 are specifyingwhich audio files are being played to the user. The intensity parameter20 controls how much audio information will be played at any given time.The variation parameter 30 controls which variation of audio informationwill be played at any given time.

FIG. 2 shows a flow diagram of a method for dynamic modification of anaudio content theme. The audio content theme comprises audio informationrelating to at least one theme variation. The method comprises thefollowing steps: Receiving at step S1 an intensity parameter 20indicative of an amount of audio information being played and avariation parameter 30 indicative of at least one theme variation of theaudio information being played; Modifying at step S2, based on saidintensity parameter 20, the amount of audio information being played,and, based on said variation parameter 30, the at least one themevariation of the audio information being played.

According to one example, the audio content theme comprises a pluralityof audio files, related to the same theme variation. Each audio filecomprises a different amount of audio information, such that, whenmodifying the intensity parameter 20, the at least one audio file beingplayed is changed to at least one audio file comprising a differentamount of audio information. Modifying the amount of audio informationbeing played may comprise: modifying the frequency of notes being playedby changing which of the at least one audio file that is being played;modifying complexity, sonic structure or harmonic content of audioinformation being played, by changing which of the at least one audiofile that is being played; modifying the plurality of instruments beingplayed at the same time by changing which of the at least one audio filebeing played; and/or modifying the amplitude of the audio informationbeing played without changing which of the at least one audio file thatis being played.

According to another example, the audio content theme comprises aplurality of audio files related to the theme variation of the audioinformation being played, wherein the theme variation can be modified bymodifying the variation parameter 30. Further, the audio content thememay comprise a plurality of audio files, related to the same amount ofaudio information, each of which audio file comprising a different themevariation, such that, when modifying the variation parameter 30, the atleast one audio file being played is changed to at least one audio filecomprising a different theme variation.

The modifying of the at least one theme variation of the audioinformation being played may comprise: modifying the combination ofmusic instruments being played by changing which of the at least oneaudio file that is being played; and/or modifying complexity, sonicstructure or harmonic content of audio information being played, bychanging which of the at least one audio file that is being played.

FIG. 3 shows an example of a view of the amplitude change of a musicfile as presented to a user of the computer program. Upwards representsamplitude and rightwards represents the intensity parameter 20. Themusic file is in this example illustrated by three regions X, Y and Z.When being in the region of X, a change to the right, which indicatesincrease in the intensity parameter 20, results in larger amplitudeincrease of the music file. When being in the region of Y, a change tothe right, which indicates to increase in the intensity parameter 20,results in smaller amplitude increase of the music file. Finally, whenbeing in the region of Z, a change to the right results in an amplitudedecrease of the music file.

According to one example, the user may change the slope of the regionsX, Y, Z in order to modify the amplitude change when moving to the rightor left in a variation.

FIG. 4 shows an example of a composer view 40 of the computer program 10comprising a plurality of audio files for the amount of audioinformation being played and plurality of audio files for themevariations of the audio information being played. There are a pluralityof audio files in each of variation A, variation B and variation C. Theaudio files, within the same variation, only differ from each other byhaving different amount of audio information being played. Those audiofiles may be labelled with an intensity level, wherein a higherintensity level represents a higher amount of audio information beingplayed. In the example of FIG. 4 there are six intensity levels, level1-6, within each variation. Each one of the plurality of audio files,related to the amount of audio information, that is played, may bemodified by the intensity parameter 20. The audio files within the sameintensity level only differ from each other by having different themevariations of audio information being played. Each one of the pluralityof audio files that is played, related to the theme variation of theaudio information being played, may be modified by the variationparameter 30.

According to one example, where only one music file is played only theamplitude of the music file being played is changed, when modifying theintensity parameter 20 as illustrated by FIG. 3. According to anotherexample, where two music files are played at the same time the amplitudeof one of the music files increases and the amplitude of the other ofthe music files decreases, when modifying the intensity parameter 20 asillustrated in FIG. 4 by each of the crossing of two music files forminga transfer region, such as for example the transfer region betweenintensity level 1 and intensity level 2 within variation A or thetransfer region between intensity level 4 and intensity level 5 withinvariation C. Hence, a smooth transition called crossfade between musicfiles within one variation can be achieved.

According to an example, the user may change each of the crossing slopesin the transfer region between two music files in order to modify theamplitude change of each of the two music files when moving to the rightor left in a transfer region within a variation.

According to another example, where two music files are played at thesame time the amplitude of one of the music files increases and theamplitude of the other of the music files decreases, when modifying thevariation parameter 30 as illustrated in FIG. 4 by each of the crossingof two music files forming a transfer region, such as for example thetransfer region between variation A and variation B within intensity 1or the transfer region between variation B and variation C withinintensity 5. Hence, a smooth transition called a crossfade between musicfiles within one intensity level can be achieved.

The audio files are constructed and composed in such a way that thelowest intensity level only consists of very little musical information.A solo violin or some high pitched piano notes for example. The audiofile(s) on the next intensity level comprises what is in the first levelbut with added audio material. The added audio material may be forexample a few more notes on the violin or a piano chord. The audiofile(s) on every further intensity level comprises even further addedaudio material. The computer program 10 crossfades between the intensityaudio files to create a seamless transition over time.

The variations are versions of the music that, in different ways, areable to play together with each other. Crossfades are also made betweenvariations A, B and C. In that way the control pad is created that makesit possible to move around in the theme in any two-dimensionaldirection, resulting in that crossfades between intensities andvariations can occur at the same time. According to a further example, aplurality of audio files are being played at the same time and whereinmodifying theme variation being played comprises increasing theamplitude of one of the plurality of audio files being played which isrelated to one variation and decreasing the amplitude of another of theplurality of audio files being played which is related to anothervariation. An advantage associated with this functionality is that asmoother transition between the audio files can be obtained, whichenhances the audio experience of the user.

Below follows an example of an audio content theme where the intensityis implemented by audio files on six different intensity levels:

-   -   Intensity one: Ambient feeling without too much rhythm or bass.        Audio information is kept to a minimum.    -   Intensity two: Elements of chords and melodies are added.        Rhythms and drums are avoided.    -   Intensity three: The musical intentions should be fairly obvious        by now. Rhythmical elements are introduced.    -   Intensity four: A “medium” version of the music. Bass should be        present at this point.    -   Intensity five: A full representation of the audio content theme        containing all elements but still with that last level held        back.    -   Intensity six: Maximum climax of the variation

There are generally two types of musical elements in an audio contenttheme. Some musical elements should create the variation between A, Band C. Other musical elements should work as glue for the whole audiocontent theme. Variations A, B and C may have three different rhythmicelements. Further, variations A, B and C may have a pad that is the samein all variations and makes the audio content theme unified.

Variations can be implemented in many different ways. Below is anexample of variations:

-   -   Variation A: Piano only    -   Variation B: Piano and strings    -   Variation C: Piano, strings and percussion

The tones of the piano may be the same in variation A, B and C.Likewise, the tones of the strings may be the same in variation B and C.

FIG. 5 shows an example of a graphical user interface 50 of the computerprogram 10 for modifying an intensity parameter 20 indicative of anamount of audio information being played and a variation parameter 30indicative of at least one theme variation of the audio informationbeing played. The computer program 10 may be configured to control agraphical user interface 50 of the computer device 10 for visualizationof the intensity parameter 20 and the variation parameter 30. Theintensity and variation parameters 20, 30 may be manually adjustable byat least one graphical input indicator 55 on said graphical userinterface 50. According to the example of FIG. 5, the graphical userinterface 50 comprises a two-dimensional coordinate system, wherein onedimension represents the intensity parameter 20 and the other dimensionrepresents the variation parameter 30. The at least one graphical inputindicator 55 is constituted by a graphical coordinate indicator beingmovable on the graphical user interface 50 in any two-dimensionaldirection. The graphical user interface 50 is built up by the musicfiles of the composer view 40 in FIG. 4. However, in the graphical userinterface 50 it is not possible to change the crossing slopes in thetransfer region between two music files. Up to four music files can havean amplitude larger than zero at the same time if the graphicalcoordinate indicator is situated in between two intensity parameter 20and two variation parameter 30.

If the computer program is started at variation A, intensity 1 (A1), asshown in FIG. 5, then only the music file A1 has amplitude larger thanzero. If the position of the graphical coordinate indicator is moved uptowards variation A, intensity 2 (A2), then the amplitude of the musicfile A1 is decreased, while the amplitude of the music file A2 isincreased. When the graphical coordinate indicator has been moved to A2,then only the music file A2 has amplitude larger than zero. If theposition of the graphical coordinate indicator is moved up towardsvariation A, intensity 3 (A3), then the amplitude of the music file A2is decreased, while the amplitude of the music file A3 is increased.When the graphical coordinate indicator has been moved to A3, then onlythe music file A3 has amplitude larger than zero. If the graphicalcoordinate indicator is moved towards variation A, intensity 6, the sameprocedure regarding decrease and increase of music files respectivelytakes place for each music file on each intensity level. Consequently,if the graphical coordinate indicator is moved to a lower intensity thenthe amplitude of the music files is crossfaded towards the lowerintensity. If the graphical coordinate indicator is positioned onvariation B, intensity 5 (B5), then only the music file B5 has amplitudelarger than zero. If the position of the graphical coordinate indicatoris moved down towards variation B, intensity 4 (B4), then the amplitudeof the music file B5 is decreased, while the amplitude of the music fileB4 is increased. When the graphical coordinate indicator has been movedto B4, then only the music file B4 has amplitude larger than zero. Thesame applies the graphical coordinate indicator is moved betweendifferent variations. If the graphical input indicator 55 is positionedon variation B, intensity 4 (B4), then only the music file B4 hasamplitude larger than zero. If the position of the graphical coordinateindicator is moved to the right towards variation C, intensity 4 (C4),then the amplitude of the music file B4 is decreased, while theamplitude of the music file C4 is increased. When the graphicalcoordinate indicator has been moved to C4, then only the music file C4has amplitude larger than zero.
